Using the External State Analyzer
To control the external analyzer with the emulator/analyzer interface
"External Analyzer" section, answer "yes" to the "Modify external analyzer
configuration?" question.
This section describes how to:
•
Specify whether the emulation emulator/analyzer interface should control
the external analyzer.
•
Specify the threshold voltages for the external channels.
•
Select the external analyzer mode.
•
Specify the slave clock mode when configured as an independent state
analyzer.
•
Define labels for the external analyzer channels.
To control the external analyzer with the
emulator/analyzer interface
•
Choose "yes" or "no" for the "Should emulation control the external
bits" configuration option.
Answer "yes" if the emulation emulator/analyzer interface should control the
external analyzer. You must answer "yes" to access the remaining external
analyzer configuration questions. At the end of the configuration process the
external analyzer mode and threshold voltages will be set; existing labels will
be deleted, and only the labels specified in response to the questions below
will be defined.
Answer "no" if the emulation emulator/analyzer interface shouldn't control
the external analyzer. If emulation does not control the external bits, the
external analyzer configuration will not be modified in any way by the
emulation interface.
To specify the threshold voltage
Choose "yes" for the "Should emulation control the external bits"
1
configuration option.
Enter the "Threshold voltage for bits 0-7 and J clock" value.
2
Enter the "Threshold voltage for bits 8-15 and K clock" value.
3
The external analyzer probe signals are divided into two groups: the lower
byte (channels 0 through 7 and the J clock), and the upper byte (channels 8
